Methods of manufacturing a belt include, at least, laying up a plurality of cords of a belt build on a mandrel, laying up a tape adhesive on an inner surface of the plurality of cords, laying up a cushion layer on an opposing side of the tape adhesive, and vulcanizing the belt build in a profile-forming mold, where the tape adhesive is a vulcanizable rubber which is devoid carbon black. The methods may further include laying up an outer tape adhesive before the laying up of the plurality of cords, and in some aspects, tension layer is laid up before laying up the outer tape adhesive. In some other methods, the tension layer is laid up before the laying up of the plurality of cords. The methods may further include partially or fully wrapping the belt with a belt wrap prior to vulcanizing the belt.

A method for manufacturing a cogged V-belt having a plurality of cogs, includes: an unvulcanized sleeve formation step of forming an unvulcanized sleeve by laminating a plurality of unvulcanized rubber sheets that contain at least an unvulcanized rubber sheet for a compression rubber layer and an unvulcanized rubber sheet for a tension rubber layer; a vulcanized sleeve formation step of forming a vulcanized sleeve by vulcanizing the unvulcanized sleeve; and a cog formation step of forming the plurality of cogs on the compression rubber layer after the vulcanized sleeve forming step.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. The weed seed destructor is driven with a straw management system from an output shaft of the combine harvester so that the full power required for both passes through a belt which includes more than four longitudinally extending v-belt ribs and reinforcing cords located in a base band above the ribs at uniformly spaced positions across the width of the belt so that a replacement drive pulley on the output shaft has a width not significantly greater than a conventional output pulley which it replaces.

A composite comprises: at least one reinforcing element (10), an adhesive layer (14) made from an adhesive composition and coating the reinforcing element (10), an elastomeric bonding layer (16) made from an elastomeric bonding composition and directly coating the adhesive layer (14), and an elastomeric body made from an elastomeric matrix and embedded in which is the reinforcing element (10) coated with the adhesive layer (14) and with the elastomeric bonding layer (16). The adhesive composition comprises a phenol-aldehyde resin based: on an aromatic polyphenol comprising at least one aromatic ring bearing at least two hydroxyl functions in the meta position relative to one another, the two positions ortho to at least one of the hydroxyl functions being unsubstituted; and on an aromatic aldehyde bearing an aldehyde function, comprising at least one aromatic ring.

belts and methods of manufacturing the same are described herein. The belt generally includes a base layer having a plurality of surface features (e.g., ribs or teeth) formed on a front surface of the base layer, and a stretched surface layer disposed on and conforming to the surface features. The stretched surface layer may comprise a knit fabric material that is from about 3 to about 10 wt. % elastomeric fiber or yarn and from about 90 to about 97 wt. % non-elastomeric yarn or fiber. The stretched surface layer is stretched over the front surface of the base layer such that the surface density of the stretched surface layer on the front surface is from about 100 to about 150 g/m.sup.2. Manufacturing methods for producing the belt with stretched surface layer generally includes disposing the surface layer on a planar front surface of the base layer and pressing a mold into the front surface of the base layer to thereby form a plurality of surface features in the front surface of the base layer. The molding step is carried out such that surface density of the surface layer on the front surface is in the range of from about 100 to about 150 g/m.sup.2 and such that the surface layer is stretched in at least two directions.

A power transmission belt includes a stacked body including a back surface layer disposed on a back surface side, an inner surface layer disposed on an inner surface side, and a tension member layer containing a tension member embedded between the back surface layer and the inner surface layer, in which the power transmission belt includes a sensor configured to detect a status of the power transmission belt, as at least a part of the stacked body.
